BACKGROUND Field of the Invention

The present disclosure generally relates to bathing devices and more particular relates to a roll-in shower apparatus.

Related Art

Lavatory devices that assist in bathing or showering are common among the elderly and disabled patient population. The National Center for Health Statistics has reported that about 10 percent of all people over the age of 65 have difficulty bathing, and about 6 percent receive help. In an assessment of home aids, adaptations and personal assistance received after traumatic spinal cord injury (SCI) in a population of 2.5 million inhabitants in Denmark, the most common aids or adaptations reported were related to the bathtub or shower (69%). Despite the increased awareness for bathroom assistance, no room at home poses more threats to safety than the bathroom. The National Safety Council reports that 7.8% of all injury episodes in the bathroom involved persons of age 65 or older. This is because the greatest danger in the bathroom is slipping and falling when entering and exiting the bathtub or shower.

To meet the needs of the aging population, the home health care services industry has grown from 40.8 million dollars in 2005 to 57.2 million dollars in 2009. Similar growth is predicted into the future based on the growing number of aging individuals entering retirement and desiring to stay within their homes. During this same period, the accessible bathtub and shower industry grew from 119.1 million dollars in 2005 to 148.5 million dollars in 2010. A similar growth rate was seen in the bath and pool lift industry that grew from 36.6 million dollars in 2005 to 45.6 million dollars in 2010. This growth rate of 4.5% per year is projected to continue as the boomers retire.

Individuals with spinal cord injury/dysfunction (SCID) confront equivalent or even more significant challenges in the bathroom. The fixtures being developed by the design team will also serve this estimated population of 262,000 persons with SCID (National Spinal Cord Injury Statistics Center). There are approximately 12,000 new cases of spinal cord injury each year. Of these injuries, 51.9% are tetraplegia and 45.2% are paraplegia (National Spinal Cord Injury Statistics Center). This level of injury leads to diminished abilities and, in some cases, individuals will require caregiver assistance for bathing and other activities of daily life. The National Spinal Cord Injury Statistics Center (NSCISC) in Birmingham, Ala., tracks over 91% of this population as living in private residences. The need to remain in the home is as compelling for a spinal cord injured patient as it is for the aging, prolonging independence, reducing health care costs and maintaining a high quality of life.

Additionally, it is estimated that approximately 90% of nursing home residents have trouble bathing and bathing disability is a strong predictor of long-term nursing home admission. Assistive technology is used to increase independence and decrease burden of care; however, an equitable system for providing assistive devices among the elderly and patients with SCID is lacking. With the advent of new technologies that promote greater independence while maintaining high safety standards, patients are more willing to invest in assistive bathing devices within the home or outpatient facility.

Therefore, what is needed is a system and method that overcomes these significant problems found in the conventional systems as described above.

SUMMARY

The present invention describes a modular roll-in shower system designed for elderly individuals or SCID patients or any individual who uses a shower wheelchair for bathing and showering. The modular roll-in shower system does not require any major bathroom modification, and can be installed anywhere in a home where hoses can be connected to a water source and a drain.

The modular roll-in shower system contains several features that assist bathers in transferring or self-propelling safely into the shower and proceeding with showering from the wheelchair position. These features include dimensions to accommodate the extra width of a wheelchair (e.g., 228 cm×95 cm doorway), an angled floor and water trough for drainage, and an appropriately-sized door handle to facilitate opening the door and entering the modular roll-in shower system.

Two design features that distinguish the modular roll-in shower system from conventional roll-in showers are: 1) hands-free self-opening and closing door, and 2) side wall openings and hinged or removable translucent windows to facilitate access by a caregiver. These two unique features provide significant advantages of the present modular roll-in shower system over conventional roll-in showers because they provide the bather with a customizable level of bathing support and also provide optional independent bathing or caregiver assistance in the bathing and showering procedure.

The angle of the door handle positioned on the outside of the modular roll-in shower system enables a convenient reach and grasp by a bather from a wheelchair position to open the shower door before entering the modular roll-in shower system. After opening the door and rolling into the modular shower system, the bather does not have to close the door. The weight of the door, which is mounted at a 3° angle, works with the hinges to swing the door closed behind the bather, hands-free. Once closed, the door engages the door-jam to provide a seal that prevents water from leaving the modular shower system. After the shower is complete, the bather can exit, hands-free, by using his/her wheelchair wheels to bump into the door and push it open from the inside.

The sidewall openings on the roll-in shower allow for the bather to see outside and the sidewall openings also provide caregiver access to assist the bather with bathing/showering. The modular roll-in shower system includes plastic translucent windows that slide into the openings in the walls. While these windows fit snugly to prevent water from leaving the modular shower system, they can also be easily opened or removed to achieve caregiver access to the bather. In one embodiment, the windows are composed of a smooth or corrugated clear or slightly opaque polymer that provides enough visibility to see in and out of the shower. Alternatively, the windows may be configured as one-way mirrors so the bather can see out but people cannot see in.

Other features and advantages of the present invention will become more readily apparent to those of ordinary skill in the art after reviewing the following detailed description and accompanying drawings.
